BeeksHELf Guide it 7 arid
falerant of arid conditions ;
by E Weiss Margraf Scientific Publishers, Weikersheim, Germany (1989) 543 pp, hardback.
Arid and semi-arid lands constitute 50% of tropical Africa and support over 35% of its population. Increasing livestock populations put tremendous pressure on these drylands which now face constant ecological degradation through overexploitation. It is this insidious process of desertification that turns marginal crop and pasture land into wasteland, reduces the quality of life of the people and threatens their survival.

Rehabilitation of degraded areas is essential and to achieve this, the identification of drought resistant plants is important. Information on the plant species of arid and semi-ari lands has been published previously, but not in easily accessible format. This publication compiles a summary of plants reported to tolerate arid or sem-ari condtion, gives a (very) brief guide to the uses these plants might have, but most usefully, serves as an identification guide to the plant species: about 500 of them are illustrated.

The large size and weight (1.6 kg) of this book make it rather cumbersome for field use, but it is a most useful reference text. The book does not mention melliferous value in any way. Species are merely categorised according to whether they have any of six potential uses, one of which is fodder/forage.

The texts of 59 papers and 23 posters presented at the Symposium held in The Netherlands in August 1990. Papers are grouped according to subject: The use of insects as pollinators, Management of solitary bees and bumblebees, Commercial production of seeds and fruits using solitary bees and bumblebees, Commercial production of seeds and fruits using honeybees, Plants in their relation to pollinators, and Insect pollination in relation to plant breeding. Papers within the Proceedings relate to temperate and tropical crop plants, and species of bees other than Apis mellifera are considered.
These Proceedings provide a concentrated guide to current pollination science. They will be of value to those involved with research into plant-bee relationships or the management of bee species for pollination.
